A 74-year-old man admitted for obstructive jaundice. After percutaneous transhepatic bilialy drainage, complete obstruction was detected at the hepatic hilus. Because of highly extension of the tumor we could not do the curative operation. So, intra biliality irradiation (8Gy, 4 times) was performed and Expandable Metallic Stent (EMS) was put into the intrahepatic to common bile duct. But five months later obstructive jaundice took place and PTCD was done once again. Microwave tissue coagulation therapy via percutaneous transhepatic cholangioscopy was performed bacause bile duct re-endoprosthesis was difficult in this time. Obstructive jaundice had not been occurred for seven months after microwave coagulation therapy. Endoprosthesis was performed by this treatment with safe. This treatment, farthermore anti-cancer effect was suggested, too.
